The size of current plates is 390 millimeters by 140 millimeters.
Passenger, 1994
On the 1994 base, the letters of passenger plate serials indicated the village of issuance. These three-letter codes were displayed in a smaller font size than was the numerical portion of the plate serial.
On the 2009 base, the letters of passenger plate serials again indicate the village of issuance. These two-letter codes are displayed in the same font size as is the numerical portion of the plate serial.
Non-passenger
On the 1994 base, commercial truck plates were coded by location of issuance, but using a different geographical coding system than for passenger plates. These codes were based on more specific geographical areas or geographical features, rather than political jurisdictions.
Bus, dealer, taxi, and trailer plates were coded only by type, not location of issuance.
